Replace default 2D detector properties with 3D overwrites

[pfaion]

This PR sets the default 2D detector properties to the same values as the 3D detector overwrites them with. This will allow a standalone 2D detector to work with a standalone 3D detector in the same way as it works currently by default.

Specific values changed (old -> new)

• strong_perimeter_ratio_range_min: 0.6 -> 0.8
• strong_area_ratio_range_min: 0.8 -> 0.6
• ellipse_roundness_ratio: 0.09 -> 0.1
• initial_ellipse_fit_treshhold: 4.3 -> 1.8
• final_perimeter_ratio_range_min: 0.5 -> 0.6
• final_perimeter_ratio_range_max: 1.0 -> 1.2
• ellipse_true_support_min_dist: 3.0 -> 2.5
